Survival outcomes in sinonasal carcinoma with neuroendocrine differentiation: A NCDB analysis.

BACKGROUND: Sinonasal carcinoma with neuroendocrine differentiation (SCND) is a rare group of tumors with poor prognosis. Treatment and sequence of therapies are still unclear. The goal of this study is to analyze treatment outcomes in SCND using a national database. METHODS: The National Cancer Database was queried for SCND from 2004 to 2014. Patient demographics, tumor characteristics and treatment paradigms were tabulated. Multivariable Cox proportional hazards regression was performed for statistical analysis of treatment regimen on overall survival (OS). RESULTS: A total of 415 patients were identified. Most patients were male (61.2%), with a median age of 58 years and the most common primary site was the nasal cavity (52.5%). T4 tumors were observed in 67.7% of cases. Unimodality (41.9%) and bimodality (43.9%) therapies were the most common treatment modalities. Radiation therapy was the only treatment administered in 30% of the patients, while 27.2% received definitive chemoradiation (CRT) and 11.6% had surgery with adjuvant CRT. In our Cox-PH model, age (HR = 1.04, p < 0.001), T4 (HR = 2.6, p = 0.004) and N2/N3 (HR = 2.18, p = 0.001) were associated with worse survival. Trimodality (HR = 0.49, p = 0.005) and bimodality (HR = 0.65, p = 0.009) therapies had a better OS compared to unimodality. Patients treated with definitive CRT or surgery with adjuvant CRT had a significant increase in OS (p = 0.01 and 0.002 respectively). CONCLUSION: SCND appears to be best treated using a multimodality approach with definitive CRT or surgery followed by CRT. Neoadjuvant chemotherapy could be helpful in selecting the best treatment strategy.

Free dermal fat graft reconstruction of the head and neck: An alternate reconstructive option.

OBJECTIVES: Ablative procedures of the head and neck often result in significant facial and cervical irregularities and cosmetic asymmetry. The deformity resulting from ablative procedures of the head and neck is a significant source of cosmetic morbidity and postoperative dissatisfaction. Reconstruction of post-ablative defects in the head and neck can employ a broad range of techniques, ranging from primary closure to free tissue transfer. The free dermal fat graft (FDFG) is one such option and has been used to repair volume defects of varying sizes after common head and neck procedures such as parotidectomy. However, its use is largely undocumented in the literature. We seek to further illustrate the FDFG as an alternate method of reconstruction of head and neck defects. STUDY DESIGN: Non-randomized retrospective analysis. METHODS: The medical records of all patients who underwent primary autologous abdominal FDFG reconstruction of head and neck defects by a single surgeon at Vanderbilt University Medical Center from January 1997 to August 2010 were reviewed. All patients were called in order to assess their post-operative cosmetic satisfaction. RESULTS: Sixty-two patients were analyzed. Only three patients were found to have post-operative complications directly related to the FDFG. No complications were found at the donor site. Based on a telephone survey, the majority of patients were satisfied post-operatively with their cosmetic outcomes in the primary site and donor site. CONCLUSIONS: From our experience the FDFG is a cosmetically and functionally advantageous option for reconstruction of ablative procedures of the head and neck.

Using a rhabdomyosarcoma patient-derived xenograft to examine precision medicine approaches and model acquired resistance.

BACKGROUND: Precision (Personalized) medicine has the potential to revolutionize patient health care especially for many cancers where the fundamental disease etiology remains either elusive or has no available therapy. Here we outline a study in alveolar rhabdomyosarcoma, in which we use gene expression profiling and a series of drug prediction algorithms combined with a matched patient-derived xenograft (PDX) model to test bioinformatically predicted therapies. PROCEDURE: A PDX model was developed from a patient biopsy and a number of drugs identified using gene expression analysis in combination with drug prediction algorithms. Drugs chosen from each of the predictive methodologies, along with the patient's standard-of-care therapy (ICE-T), were tested in vivo in the PDX tumor. A second study was initiated using the tumors that re-grew following the ICE-T treatment. Further expression analysis identified additional therapies with potential anti-tumor efficacy. RESULTS: A number of the predicted therapies were found to be active against the tumors in particular BGJ398 (FGFR2) and ICE-T. Re-transplanted ICE-T treated tumorgrafts demonstrated a decreased response to ICE-T recapitulating the patient's refractory disease. Gene expression profiling of the ICE-T treated tumorgrafts identified cytarabine (SLC29A1) as a potential therapy, which was shown, along with BGJ398, to be highly active in vivo. CONCLUSIONS: This study illustrates that PDX models are suitable surrogates for testing potential therapeutic strategies based on gene expression analysis, modeling clinical drug resistance and hold the potential to assist in guiding prospective patient care.

Mind-Body Therapies in the Management of Otolaryngologic Disease: A State-of-the-Art Review of Randomized Controlled Trials.

OBJECTIVE: To review and assess the peer-reviewed literature on the utility of mind-body therapy (MBT) as an adjunct treatment in the management of otolaryngologic disease. DATA SOURCES: PubMed, Embase, and Cochrane. REVIEW METHODS: Randomized control trials (RCTs) of MBTs in the management of otolaryngologic disease from 2002 to 2022 were identified and included according to predefined criteria. Interventions requiring expensive equipment were excluded because the goal of MBT is to be cost-conscious. All studies were subjected to a two-stage blinded screening, extraction, and appraisal process. The outcomes of the intervention and control groups were compared. CONCLUSION: RCTs of MBTs, including breathing exercises (4), aromatherapy (2), biofeedback (2), meditation, (2), and yoga (2), have been studied in several otolaryngologic conditions, including septoplasty/rhinoplasty (3), head and neck cancer (2), facial palsy (2), and tinnitus (2). Most studies were of moderate risk of bias on appraisal, and each MBT studied was found to significantly reduce subjective and objective distress associated with the otolaryngologic condition in question. IMPLICATIONS FOR PRACTICE: Despite a paucity of strong evidence supporting the universal use of MBTs, our review suggests that MBTs are cost-effective and easily deployable complementary tools in the management of otolaryngologic disease. Future large, methodologically rigorous RCTs are needed to address the limitations of the included studies, such as improper blinding and inappropriate statistical analysis. As MBTs are studied further, a case for their current use can be made because of their low cost and minimal risk to patients.

The utility and accuracy of ChatGPT in providing post-operative instructions following tonsillectomy: A pilot study.

OBJECTIVE: To investigate the utility of answers generated by ChatGPT, a large language model, to common questions parents have for their children following tonsillectomy. METHODS: Twenty Otolaryngology residents anonymously submitted common questions asked by parents of pediatric patients following tonsillectomy. After identifying the 16 most common questions via consensus-based approach, we asked ChatGPT to generate responses to these queries. Satisfaction with the AI-generated answers was rated from 1 (Worst) to 5 (Best) by an expert panel of 3 pediatric Otolaryngologists. RESULTS: The distribution of questions across the five most common domains, their mean satisfaction scores, and their Krippendorf's interrater reliability coefficient were: Pain management [6, (3.67), (0.434)], Complications [4, (3.58), (-0.267)], Diet [3, (4.33), (-0.357)], Physical Activity [2, (4.33), (-0.318)], and Follow-up [1, (2.67), (-0.250)]. The panel noted that answers for diet, bleeding complications, and return to school were thorough. Pain management and follow-up recommendations were inaccurate, including a recommendation to prescribe codeine to children despite a black-box warning, and a suggested post-operative follow-up at 1 week, rather than the customary 2-4 weeks for our panel. CONCLUSION: Although ChatGPT can provide accurate answers for common patient questions following tonsillectomy, it sometimes provides eloquently written inaccurate information. This may lead to patients using AI-generated medical advice contrary to physician advice. The inaccuracy in pain management answers likely reflects regional practice variability. If trained appropriately, ChatGPT could be an excellent resource for Otolaryngologists and patients to answer questions in the postoperative period. Future research should investigate if Otolaryngologist-trained models can increase the accuracy of responses.

The Use and Utility of Food and Drug Administration Adverse Event Data from the Manufacturer and User Facility Device Experience Database in Otology: A Systematic Review.

OBJECTIVE: To review otology-related studies using the US Food and Drug Administration's Manufacturer and User Facility Device Experience (MAUDE) database to identify the opportunities and limitations of using MAUDE. DATABASES REVIEWED: PubMed, Science Direct, Web of Science, SCOPUS, and EMBASE. METHODS: All studies reporting otology-related adverse events extracted from MAUDE were included from June 20, 2002, to 2022. Two reviewers independently screened abstracts, selected articles for exclusion, extracted data, and appraised studies. Critical appraisal was done according to the National Institutes of Health quality assessment tool for case series. RESULTS: The search yielded 5,645 studies, of which 8 studies met the inclusion criteria. All eight studies were case series; three evaluated cochlear implants, two evaluated osseointegrated hearing implants, and one evaluated illuminated operating microscope use. Quality assessment revealed all studies to be of poor quality. The most common domains contributing to these ratings included unclear study population, lack of consecutive participants, comparability of participants, clear and consistent outcome measures, and appropriate statistical analysis. CONCLUSION: Otology studies using the MAUDE database are of poor quality. This was primarily due to MAUDE's structural limitations as a passive surveillance system using nonstandardized free-text reports. The quality of studies also suffered from inappropriate analysis of MAUDE data, given its design. The utility of MAUDE could be improved by implementing case report best practices and converting the free fields to allow controlled and adaptive responses wherever possible to help standardize adverse event reporting.

Preoperative Embolization Techniques in the Treatment of Juvenile Nasopharyngeal Angiofibroma: A Systematic Review.

OBJECTIVE: Preoperative embolization has proven beneficial in the surgical treatment of juvenile nasopharyngeal angiofibromas (JNA). However, the consensus for the best embolization practices remains unclear. This systematic review seeks to characterize the reporting of embolization protocols throughout the literature and to compare differences in surgical outcomes. DATA SOURCES: PubMed, Embase, and Scopus. REVIEW METHODS: Studies investigating embolization in the treatment of JNA from 2002 to 2021 were selected from defined inclusion criteria. All studies underwent a 2-stage blinded screening, extraction, and appraisal process. Embolization material, time to surgery, and embolization route were compared. Embolization complications, surgical complications, and rate of recurrence were pooled. RESULTS: Of 854 studies, 14 retrospective studies with 415 patients met the criteria for inclusion. A total of 354 patients underwent preoperative embolization. A total of 330 patients (93.2%) underwent transarterial embolization (TAE) and 24 patients had a combination of direct puncture embolization and TAE. Polyvinyl alcohol particles were the most used embolization material (n = 264, 80.0%). The most common reported time to surgery was 24 to 48 hours (n = 8, 57.1%). Pooled results showed an embolization complication proportion of 3.16% (95% confidence interval [CI]: 0.96-6.60) (n = 354), a surgical complication proportion of 4.96% (95% CI: 1.90-9.37) (n = 415), and a recurrence proportion of 6.30% (95% CI: 3.01-10.69) (n = 415). CONCLUSION: The current data on JNA embolization parameters and their effect on surgical outcomes remains too heterogenous to provide expert recommendations. Future studies should use uniform reporting to allow for more robust comparisons of embolization parameters, which, in turn, may lead to optimized patient outcomes.

Nasal Cavity Squamous Cell Carcinoma: Factors Associated With Treatment Outcomes and Potential Organ Preservation.

BACKGROUND: Squamous cell carcinoma of the nasal cavity (NCSCC) is a rare, challenging malignancy. Surgical resection of this tumor can cause significant facial deformity, and indications for adjuvant or organ preservation therapies are not well-described. OBJECTIVE: To examine the impact of treatment regimen on survival outcomes in NCSCC and to compare surgical to non-surgical based therapies. METHODS: The National Cancer Database was queried for NCSCC from 2004 to 2014. Patient demographics, tumor characteristics, and treatment regimen were compared for the entire cohort. Multivariable Cox proportional hazards regression was performed for statistical analysis of treatment regimen and surgical margins on overall survival (OS) for early and late-stage disease. RESULTS: A total of 1883 NCSCC patients were identified. The OS for the cohort was 83 months, and median age at diagnosis was 65 years. NCSCC patients who underwent surgery followed by adjuvant radiation therapy (RT) had a better OS compared to definitive RT (HR: 0.58, P < .001). In early stage NCSCC (T1/T2, N0), there was no significant difference in OS between patients treated with surgery only or surgery with adjuvant RT compared to definitive RT. In advanced stage NCSCC, surgery with adjuvant RT had a better OS compared to definitive chemoradiation. Having positive margins was shown to predict a worse OS when compared to negative margins in surgical patients despite adjuvant RT or chemoradiation. CONCLUSIONS: NCSCC appears to be best treated with surgery followed by adjuvant RT in advanced-stage disease whereas in early-stage disease, surgery does not improve OS compared to definitive RT.

Postoperative Polyp Scale (POPS): Development of a New Sinonasal Polyp Grading Scale.

OBJECTIVE: Commonly used endoscopic grading scales, such as the nasal polyp scale, inadequately describe the degree of polyposis found postoperatively in the paranasal sinus cavities. The purpose of this study was to create a novel grading system that more accurately characterizes polyp recurrence in postoperative sinus cavities, the Postoperative Polyp Scale (POPS). METHODS: A modified Delphi method was utilized to establish the POPS using consensus opinion among 13 general otolaryngologists, rhinologists, and allergists. Postoperative endoscopy videos from 50 patients with chronic rhinosinusitis with nasal polyps were reviewed by 7 fellowship-trained rhinologists and scored according to the POPS. Videos were rated again 1 month later by the same reviewers, and scores were assessed for test-retest and inter-rater reliability. RESULTS: Overall inter-rater reliability for the first and second reviews of the 52 videos was Kf = 0.49 (95% CI 0.42-0.57) and Kf = 0.50 (95% CI 0.42-0.57) for the POPS. Intra-rater reliability showed near-perfect test-retest reliability for the POPS with Kf = 0.80 (95% CI 0.76-0.84). CONCLUSION: The POPS is an easy-to-use, reliable, and novel objective endoscopic grading scale that more accurately describes polyp recurrence in the postoperative state which will be useful in the future for measuring the efficacy of various medical and surgical interventions. LEVEL OF EVIDENCE: 5 Laryngoscope, 133:2885-2890, 2023.

Predictive Clinical and Surgical Factors Associated with Recurrent Apoplexy in Pituitary Adenomas.

Introduction Pituitary apoplexy is an uncommon clinical condition that can require urgent surgical intervention, but the factors resulting in recurrent apoplexy remain unclear. The purpose of this study is to determine the risks of a recurrent apoplexy and better understand the goals of surgical treatment. Methods A retrospective chart review was performed for all consecutive patients diagnosed and surgically treated for pituitary apoplexy from 2004 to 2021. Univariate analysis was performed to identify risk factors associated with recurrent apoplexy. Results A total of 115 patients were diagnosed with pituitary apoplexy with 11 patients showing recurrent apoplexy. This occurred at a rate of 2.2 cases per 100 patient-years of follow-up. There were no major differences in demographic factors, such as hypertension or anticoagulation use. There were no differences in tumor locations, cavernous sinus invasion, or tumor volumes (6.84 ± 4.61 vs. 9.15 ± 8.45 cm, p = 0.5). Patients with recurrent apoplexy were less likely to present with headache (27.3%) or ophthalmoplegia (9.1%). Recurrent apoplexy was associated with prior radiation (0.0 vs. 27.3%, p = 0.0001) and prior subtotal resection (10.6 vs. 90.9%, p = 0.0001) compared with first time apoplexy. The mean time to recurrent apoplexy was 48.3 ± 76.9 months and no differences in overall follow-up were seen in this group. Conclusion Recurrent pituitary apoplexy represents a rare event with limited understanding of pathophysiology. Prior STR and radiation treatment are associated with an increased risk. The relatively long time from the first apoplectic event to a recurrence suggests long-term patient follow-up is necessary.

Skull Base Registries: A Roadmap.

Hospitals, payors, and patients increasingly expect us to report our outcomes in more detail and to justify our treatment decisions and costs. Although there are many stakeholders in surgical outcomes, physicians must take the lead role in defining how outcomes are assessed. Skull base lesions interact with surrounding anatomy to produce a complex spectrum of presentations and surgical challenges, requiring a wide variety of surgical approaches. Moreover, many skull base lesions are relatively rare. These factors and others often preclude the use of prospective randomized clinical trials, thus necessitating alternate methods of scientific inquiry. In this paper, we propose a roadmap for implementing a skull base registry, along with expected benefits and challenges.

Endoscopic Endonasal Treatment of a Sinonasal Vascular Neoplasm in the Postnatal Period: Case Report and Review of Literature.

OBJECTIVES: Congenital vascular lesions commonly present in the head and neck, and most are managed conservatively. Location and rapid growth, however, may necessitate surgical intervention. Endoscopic endonasal surgery (EES) in the pediatric population has emerged as a viable option in treating sinonasal and skull base lesions. Utilizing these techniques in newborns carries unique challenges. The objective of this report is to describe the successful use of direct intralesional embolization followed by endoscopic endonasal resection of a venous malformation in a postnatal patient. METHODS: We reviewed the case reported and reviewed the pertinent literature. RESULTS: A 6-week-old infant was found to have a large right-sided sinonasal lesion confirmed as a venous malformation. Rapid growth, impending orbital compromise, and potential long-term craniofacial abnormalities demanded the need for urgent surgical intervention. Risk of bleeding was mitigated with direct intralesional embolization. Immediately afterward, the patient underwent endoscopic endonasal resection of the lesion. EES in the very young presents multiple challenges both anatomically and behaviorally. A multidisciplinary approach lead to a successful outcome. CONCLUSION: We report a case of a 6-week-old infant, the youngest reported patient to the authors' knowledge, who successfully underwent direct intralesional embolization followed by endoscopic endonasal resection of a sinonasal vascular malformation. This report highlights the challenges of this technique in the very young and demonstrates it as a viable treatment strategy for sinonasal vascular anomalies in this population.

Retrospective Review of Surgical Site Infections after Endoscopic Endonasal Sellar and Parasellar Surgery: Multicenter Quality Data from the North American Skull Base Society.

Introduction Transnasal access to the anterior skull base provides a minimally invasive approach for sellar and parasellar masses compared with its open counterparts. The unique microbiome of the sinonasal mucosa provides distinct challenges not encountered with other cranial approaches. The use of antibiotics in these cases has not been standardized, and data remain scarce regarding infectious outcomes. Methods We conducted a multicenter retrospective analysis of shared quality data points for the endoscopic endonasal approach (EEA) for pituitary adenomas, along with other sellar and parasellar region masses that were included by participating institutions. Patient and operative characteristics, perioperative and postoperative antibiotic regimens and their durations, intraoperative and postoperative cerebrospinal fluid leak, and onset of postoperative meningitis and sinusitis were compared. Results Fifteen institutions participated and provided 6 consecutive months' worth of case data. Five hundred ninety-three cases were included in the study, of which 564 were pituitary adenomectomies. The incidences of postoperative meningitis and sinusitis were low (0.67 and 2.87% for all pathologies, respectively; 0.35% meningitis for pituitary adenomas) and did not correlate with any specific antibiotic regimen. Immunocompromised status posed an increased odds of meningitis in pituitary adenomectomies (28.6, 95% confidence interval [1.72-474.4]). Conclusions The results show no clear benefit to postoperative antimicrobial use in EEA, with further larger studies needed.

Robotic-Assisted Tubular Transoral Parapharyngeal Approach to the Ventral Craniovertebral Junction.

BACKGROUND: Transoral robotic surgery (TORS) has become a routine technique for treating benign and malignant lesions of the oropharynx with the advantage of reducing morbidity compared to open surgical techniques. However, TORS has not been used routinely for accessing lesions of the spine. OBJECTIVE: To describe how TORS can be used to access spinal lesions. METHODS: We describe our technique of accessing the parapharyngeal space using the robotic technique, and then dissecting the prevertebral muscles to expose the ventral craniovertebral junction. Tubular retraction with endoscopic visualization is then employed for surgical resection. We then report a case of a 14-yr-old competitive athlete who presented with an osseous lesion of C1, which underwent resection using this novel TORS approach. RESULTS: Our patient underwent successful resection of a lateral C1 osteoid osteoma utilizing a combined TORS/endoscopic approach. She tolerated soft diet immediately and was discharged on postoperative day 2. Postoperative imaging revealed complete resection of the lesion, and she returned to competitive athletics within 6 wk. CONCLUSION: Utilizing this novel, robotic-assisted approach can definitively treat osseous cervical spine lesions while reducing morbidity, allowing for early return to normal diet and minimizing overall length of hospital stay.

Development of a self-directed sinonasal surgical anatomy video curriculum: Phase 1 validation.

BACKGROUND: Sinusitis is a common outpatient diagnosis made by physicians and is a reason for referral to otolaryngologists. A foundation in basic sinonasal anatomy is critical in understanding sinus pathophysiology and avoiding complications. Our objective in this study was to develop and to validate a self-directed surgical anatomy video for medical students. METHODS: Two multimedia videos were developed highlighting sinonasal anatomy. In Video 1 we included audio narration and radiologic imaging. Video 2 incorporated highlighted images from a sinus surgery video. An assessment was developed to test sinonasal anatomy landmarks, spatial recognition of structures, and their clinical relevance. An expert panel of rhinologists scored face and content validity of the curriculum videos and assessment. Factor analysis was used to separate questions into face and content validity domains, and a one-sample t test was performed. RESULTS: The panel scored face validity (Videos 1 and 2: 4.4/5) and content validity (Video 1: 4.5/5, 0.83; Video 2: 4.3/5, 0.75) significantly higher than a neutral response. There were no statistical differences for face or content validity between videos. The assessment was rated suitable (29%) or very suitable (57%) for testing basic sinonasal surgical anatomy, and the majority (71%) of respondents agreed (14%) or strongly agreed (57%) that the assessment thoroughly covered the sinus anatomy content with which medical students should be familiar. CONCLUSION: We have developed two videos and an assessment that highlight and test sinonasal anatomy. Future studies will aim to identify whether the use of a self-directed video curriculum improves sinonasal anatomy awareness and whether incorporation of surgical endoscopic videos augments training.

Prevalence of and Associations With Distress and Professional Burnout Among Otolaryngologists: Part II, Attending Physicians.

OBJECTIVE: To ascertain the prevalence of and associations with distress and professional burnout among academic otolaryngology attending physicians. STUDY DESIGN: Cross-sectional survey. SETTING: Twelve US academic otolaryngology programs. METHODS: A questionnaire was administered that encompassed sociodemographic and professional features, the Expanded Physician Well-being Index for distress, the 2-item Maslach Burnout Inventory for professional burnout, the Patient Health Questionnaire-2 screen for major depressive disorder, and the Generalized Anxiety Disorder-2 screen for generalized anxiety disorder. RESULTS: The survey response rate was 56% and included 186 attending physicians. The average respondent age was 47 years; 72% were men; 93% were married or partnered; and 86% had children. Distress was present in 40%, professional burnout in 26%, positive depression screening in 8%, and positive anxiety screening in 11%. In a univariable setting, age, hours worked in a typical week, nights on call in a typical week, and years of practice were significantly associated with distress, although in a multivariable setting, only hours worked in a typical week remained significantly associated with a positive Expanded Physician Well-being Index screen (odds ratio for each 10-hour increase, 2.61; 95% CI, 1.73-3.93; P < .001). In a univariable setting, hours worked in a typical week was significantly associated with a positive Maslach Burnout Inventory screen. CONCLUSION: Distress or professional burnout occurs in more than a quarter of academic otolaryngology attending physicians, whereas the prevalence of depression or anxiety is approximately 10%. The number of hours worked per week had the strongest association with distress and burnout. These findings may be used to develop and implement programs to promote physician well-being and mitigate professional burnout.

Prevalence of and Associations With Distress and Professional Burnout Among Otolaryngologists: Part I, Trainees.

OBJECTIVE: To assess the prevalence of distress and burnout in otolaryngology trainees, including associations with relevant sociodemographic and professional factors, and to compare these results with those of attending otolaryngologists. STUDY DESIGN: A cross-sectional survey of trainees and attending physicians. SETTING: Twelve academic otolaryngology programs. METHODS: Distress and burnout were measured with the Expanded Physician Well-being Index and the 2-item Maslach Burnout Inventory. The Patient Health Questionnaire-2 and Generalized Anxiety Disorder-2 were used to screen for depressive disorders and anxiety disorders, respectively. Associations with sociodemographic and professional characteristics were assessed. RESULTS: Of the 613 surveys administered to trainees and attending physicians, 340 were completed (56%). Among 154 trainees, distress was present in 49%, professional burnout in 35%, positive depressive disorder screening in 5%, and positive anxiety disorder screening in 16%. In univariable analysis, female gender, hours worked in a typical week (HW), and nights on call in a typical week (NOC) were significantly associated with distress. In multivariable analysis, female gender (odds ratio, 3.91; P = .001) and HW (odds ratio for each 10 HW, 1.89; P = .003) remained significantly associated with distress. Female gender, HW, and NOC were significantly associated with burnout univariably, although only HW (odds ratio for each 10 HW, 1.92; P = .003) remained significantly associated with burnout in a multivariable setting. Attending physicians had less distress than trainees (P = .02) and felt less callous and less emotionally hardened than trainees (P < .001). CONCLUSION: Otolaryngology trainees experience significant work-place distress (49%) and burnout (35%). Gender, HW, and NOC had the strongest associations with distress and burnout.

Trimodal embolization of juvenile nasopharyngeal angiofibroma with intracranial extension.

OBJECTIVES/PURPOSE: 1. Understand three different techniques for embolization of juvenile nasal angiofibroma (JNA) and assess their combined efficacy. 2. Perform successful endoscopic intralesional embolization of highly vascular sinonasal neoplasms. METHODS: In this study, we present the case of a 10-year-old male patient diagnosed with juvenile nasal angiofibroma (JNA) who successfully underwent trimodal embolization and resection at a tertiary academic medical center after failed coil embolization in his home country. We examine the clinical details of the case and a review of pertinent literature. RESULTS: Preoperative embolization is common in the treatment of JNA, but there is little consensus as to the proper timeframe and techniques utilized. In our case, preoperative imaging revealed a vascular tumor with intracranial extension consistent with UPMC Stage V JNA. Diagnostic angiogram revealed significant arborization from the internal and external carotid systems. A trimodal embolization technique, utilizing transarterial, percutaneous, and direct endoscopic intralesional injection of n-Butyl Cyanoacrylate (n-BCA) was performed. A two-staged endoscopic and open resection was subsequently performed one week later with minimal blood loss. In our case, combining intralesional embolization with traditional transarterial techniques resulted in an improved operative field and a successful clinical result. CONCLUSION: Embolization of highly vascular sinonasal tumors with n-BCA is not limited to endovascular techniques, but can be safely combined with percutaneous and endoscopic intralesional embolization up to one week prior to surgical resection.

Quantitative determination of the optimal temporoparietal fascia flap necessary to repair skull-base defects.

BACKGROUND: The ability to reconstruct large cranial base defects has greatly improved with the development of pedicled vascularized flaps. The temporoparietal fascia flap (TPFF) is a viable alternative to the Hadad-Bassagasteguy nasoseptal flap for large ventral skull-base defects. This study aims to characterize the size of the TPFF necessary for optimal ventral skull-base reconstruction. METHODS: Eleven formaldehyde-fixed cadaveric heads were used to harvest TPFF of varying heights on each side (total = 22). TPFF was passed through the pterygomaxillary fissure (PMF) to the ventral skull base to assess its coverage. For a subgroup of 12 sides, the TPFF was trimmed to determine the minimum height necessary for coverage. RESULTS: The TPFF height was (mean ± standard deviation [SD]) 14.72 ± 1.02 cm (range, 12.5 to 16.5 cm) and width was 8.43 ± 1.05 cm (range, 6 to 10.5 cm). The distance from the TPFF pedicle through the PMF was 5.8 ± 0.5 cm (range, 5 to 6.5 cm). All TPFF flaps provided complete ipsilateral coverage of clival defects, and all but 1 covered the entire clivus. All TPFF flaps, when rotated anteriorly, provided coverage up to the cribriform plate. The minimum TPFF height necessary for complete coverage of cribriform defects and ventral defects up to the planum sphenoidale was 12 cm. TPFF height for specimens with and without complete ventral skull-base coverage was significantly different (p < 0.0001). CONCLUSION: The TPFF is a versatile alternative to the nasoseptal flap and a height of at least 12 cm can provide enough coverage for all ventral skull base defects.
